The city is holding a "pumpkin smash" on Saturday for residents to get rid of their Halloween pumpkins and maybe take out some aggression. Free cider donuts will be on hand for replenishing your energy.

It's 11 a.m. to 2 p.m. at the Mattapan Ecovation Center, 456 American Legion Highway in Mattapan. People who have no reason to smash a pumpkin can instead put their pumpkins in with their yard waste, where it will be composted for use in city parks.

The Globe interviews a Revere man who has what is now a 500-lb. pumpkin that he plans to hollow out and use to paddle across Boston Harbor, from Jeffries Point in East Boston to the Fish Pier in South Boston.

The Coast Guard introduces us to Joanne LaVigne Schroer, who was just a little girl when her father was assigned to a two-year spell as the Boston Light lighthouse keeper. And she recalls the ghost:

"When we went out to the island [in 1948] the second-floor bedroom that faces the light itself was always locked," Schroer recalled. "We had always heard that back in the 1800s there was a lightkeeper whose wife went a little stir crazy and killed her husband right around Halloween. Then, she wrote about it in her diary.

"Every October, we would hear these weird noises in that room," Schroer said. "One night, my mother jiggled the doorknob to see what was going on. All of a sudden, this black image came right through the door, down the hallway and then down the stairs into the kitchen. It was the lightkeeper's wife, and she had a big dog with her," Schroer attested. "I woke up in the middle of the night and there was that big dog sitting right in the room."

I asked him what he was going to be for Halloween and he said, "A train!" and then immediately specified with "A green line train!!!" My sister had to tell him he was just going to be a normal train since she didn't have time to make one and couldn't find a green line train costume to buy. So I started on my quest with a $1.50 moving box and some duct tape.
